My son is on risperidone and i have recently read that it causes breast and weight gain in boys. is there something else he can take for his dbd?

Risperdal: No. Any med can do anything. If he does not have this rare side effect stick with it.

Atypical antipsycho: This entire class of medications, called atypical antipsychotics, have these potential side effects, although they are extremely rare.Even still, you need to be working with a doctor who is familiar with the possible side effects and monitoring for them. There are other mood stabilizing drug options such as some of the anti-seizure medications like tegretol, lamictal, and others. Talk to psych doc.
